Uh-oh, looks like maybe GM was onto something?
Normally Haseley gets more of the starts against RHPs (6 to Quinn's 4, Quinn with 6 against LHP). But if that was the plan they should have played Quinn yesterday, and obviously Kingery gives you no platoon advantage even if turning Quinn around makes him weaker. Maybe, despite his obvious offensive assets, they're not happy with his defense?
Absolutely, you can't play him every day, but this will be three days off in a row, so seems possible he's banged up, especially since Kingery is too.
